Advanced Biology, EarlyView.Positively supercharged mGreenLatern protein is self‐assembled electrostatically with negatively charged zinc phthalocyanines to yield bio‐based photoactive materials in aqueous media. The addition of phthalocyanines results in the formation of large complexes fully quenching of the protein fluorescence. The results indicate an energy transfer from the

Quantum Dot Self‐Assembly Enables Low‐Threshold Lasing
Advanced Science, 2021 Perovskite quantum dots (QDs) are of interest for solution‐processed lasers; however, their short Auger lifetime has limited lasing operation principally to the femtosecond temporal regime the photoexcitation levels to achieve optical gain threshold are ...

Identifying Shapes Using Self-Assembly (extended abstract) [PDF]
arXiv, 2010 In this paper, we introduce the following problem in the theory of algorithmic self-assembly: given an input shape as the seed of a tile-based self-assembly system, design a finite tile set that can, in some sense, uniquely identify whether or not the given input shape--drawn from a very general class of shapes--matches a particular target shape.

Hopping and crawling DNA-coated colloids [PDF]
arXiv, 2023 Understanding the motion of particles with ligand-receptors is important for biomedical applications and material design. Yet, even among a single design, the prototypical DNA-coated colloids, seemingly similar micrometric particles hop or roll, depending on the study.

Spatiotemporal Control Over Protein Release from Artificial Cells via a Light‐Activatable Protease
Advanced Biology, EarlyView.Stimulus‐responsive protein release is essential for intercellular communication. Mimicking this functionality in artificial cells is promising to study the working principles of cellular signaling. Herein, an engineered light‐activatable protease is implemented in a coacervate‐based artificial cell platform to establish user‐defined spatiotemporal ...

Supramolecular dissipative self‐assembly systems: Approaches and applications
Responsive Materials, 2023 Dissipative self‐assembly (DSA) system requires a continuous supply of fuels to maintain the far‐from‐equilibrium assembled state. Living organisms exist and operate far from the thermodynamic equilibrium by continuous consumption of energy taken from ...

Size-Separable Tile Self-Assembly: A Tight Bound for Temperature-1 Mismatch-Free Systems [PDF]
arXiv, 2014 We introduce a new property of tile self-assembly systems that we call size-separability. A system is size-separable if every terminal assembly is a constant factor larger than any intermediate assembly. Size-separability is motivated by the practical problem of filtering completed assemblies from a variety of incomplete "garbage" assemblies using gel ...

Kinetic Monte Carlo and Cellular Particle Dynamics Simulations of Multicellular Systems [PDF]
, 2011 Computer modeling of multicellular systems has been a valuable tool for interpreting and guiding in vitro experiments relevant to embryonic morphogenesis, tumor growth, angiogenesis and, lately, structure formation following the printing of cell aggregates as bioink particles.
